FOLDED INDEX-STRIP MACHINE AND PROCESS.

Application filed September 6, 1921. Serial No. 498,791.

My invention relates to an improvement in a process of making index tabs and the machine for carrying out such process.

Index tabs have heretofore been made by hand, and the manual process was long and tedious and necessarily expensive because ofthe large amount of labor involved. My method and device have solved this problem by furnishing an automatic method of manufacturing index tabs and a machine for carrying out such process which will turn out per day a volume of tabs greater than could heretofore be made by a large number of operators by hand in a day, and such machine requires only one operator, and then only occasionally to renew the supplies and to set up the machine in operation and stop it.

Referring to the drawings Figure 1 is a front elevation showing the entire length of the machine; Figure 2 is a top plan view of the same; Figure 3 is an end view looking in from the left hand end of Fig. 1; Fig ure 4 is a top plan view of the product; Fig ure 5 is a cross-sectional view of Fig. 4 on the line 55; Figure 6 is a detail of part of the guideway, which is broken away, and the guide arm; and Figure 7 is a vertical sectional view on the line 7-7 in Fig. 3. Fig. 8 is a vertical sectional view on the line 8-8 in Fig.6. In the drawings 10 is a table top which is rigidly secured to standards 11., and the standards 11 are rigidly secured together by means of the longitudinal connecting rods 12. To the table top 10 is rigidly secured a motor 13 of usual construction which is adapted to be driven by electric power which is not shown hereon, and in said motor 13 is mounted a shaft 14% which is driven thereby. On the outer end of the said shaft 14: is a worm gear 15.

. A'sub-frame 16 is rigidly secured at 1'7 to the tabletop 10. In the sub-frame 16 is mounted a shaft 18 in suitable bearings so that it will rotate freely, and on the outer end ofsaid shaft 18 is rigidly niountedia pinion 19 so that it will engage with the worm gear 15. A gear 20 is also rigidly mounted on the shaft 18 so that it rot-ates therewith. A second shaft 21 is mounted in suitable bearings in the sub-frame 16 so that it will rotate freely therein, and on-the outer end of said shaft is rigidly secured a gear 2:2 which is adapted to mesh with gear 20 on shaft 18 and rotate therewith. A second gear 23 is also rigidly mounted on shaft 21 just-inside of the gear 22 and travels with the rotation of said shaft 21. A third shaft 2% is mounted in guide blocks 25, which also act as bearings, which blocks 25 move in guideways 26 of sub-frame 16, the relative position of which can be changed by means of bolts 27 over which are springs 28 adapted to keep the shaft 24 under spring pressure thereby. The bolt members 2 1 are mounted in plates 29 which are bolted at 30 to the two up er ends of the sub-frame 16. On the outer end of the shaft or is rigidly secured a gear 81 which is adapted to mesh with gear 23 on shaft 21.

A pressure roller 32 is rigidly secured to the shaft 2% so that it rotates therewith, and a second pressure roller 33 is rigidly secured to the shaft 21 so that it rotates therewith and also with the roller 32 as they are an ranged to press against each other under pressure of springs 28. V Said roller 33 is of sufficient width and has flanges 3% adapted to extend beyond and overlap the sides of the roller 32 as they rotate together.

An eccentric is rigidly mounted on the shaft 18 so that it rotates therewith and is adapted to contact with and rotate with a roller 36 which is loosely mounted on a block 37 which travels in a guideway 38, and which block 37 also carries rigidly secured thereto a knife 39 and has a spring 40 mounted in. the top thereon which keeps knife 39 norinallyin the lower position. The spriu 4:0 is also mounted at its upper end to a rigid block 11 which is rigidly secured to the sub-frame 16. and said block at also carries a stationary knife 42 rigidly secured thereto. A sup porting bar is mounted by means of pins 414 under spring pressure 45 on an outturned.

lip are rigidly secured to the block 37, scam the supporting bar 1 3 readily yieldsunder pressure.

At the opposite end of the .table top 10 from the sub-frame 18 is a second subflQI1I-6-4T'Wl1lCh-l8 rigidly secured at 48 to the rotatahly moun tabletop 10. A pair oi moi telling rollers 4-9 and having absoi'bent surili'aoes are H'IOHIltBCl on shai'ts 51 and 52, which shafts are loosely mounted in sub-i? ame 4LT so that they rotate freely thereon, and so that sa'ic'l moisteniil'g rollers t?) and 50 contact with each other and turn together. A similar pair ot' moistening rollers 53 and 54 are mounted on shafts 55 and 56, which shafts are mounted in the sub-frame i? so that they irotat-e freely. Said rollers 53 and 5e are rigidly mounted on shafts 55 and 56 and rotate therewith partially Within Water pans (YT-and 58 Winch arerigidly secured to the sub-frame 47 and which pans have virespeet-ively covers '59 and 60 secured thereto with openings so that said pans 5:7 and 58 may be readily fijlled with Water. A

Pinion 6 1 is -rigidly mounted on shaft 55 so that it rotates therewith, it'iltlepllllOll 62 is rigidly mounted on shaft -56 so-that it rotates therewith. Pin-ion isrigidlymounted 011- a shaft 93 which is mounted in the subi ran e 4J7 so that it rotates freely. Pinion (S t is rigidly nounted'jon shaft 2i and rotates therewith. A chain 165 is mounted so that it runs over pinions 61, 62, -63 and 6.4.

A guideway '66 is rigidly secured to a bracket '67, and said bracket 67 is rigidly se- .eure d by means of set screws '68 in an adjustable slot 69 to an upright 70 Which is rigidly secured to thetable top at 71.

The guideway 60 has a neck portion 72 adapte'd to form the material runn in g theret-hrough to-a position ready :tor folding. A post "(F3 is rigidly secured to the table top -1Q,- and 'a guide arm 74 is rigidly secured toisaid post 73 by means of .aholt and wing -nut 7'5. The guide arm 74 i-has a-groove =or lip member 76wvhich is adaptedto guide into its proper position, hei ore sealing, a core member -87 of the tale. A hinged tension member 77"is rigidly secured to the subframe 16 at 78, and the tension plate or hinge member 7 9 is held under tension hy means of spring compression screws '80.

T he machine is now set up ready for the operation, and by turning on the power shaft- 14; is set in motion, which motion is transmitted through the worm gear 15' and :pinion 19 to the shaft 18 which turns the gear 20, which in turn drives the ,gear 22 in the opposite direction. 21 and alsothe gear'IQS thereon which meshes with gear ;-31, and whidh is turned itherehy.

As the :pinion "6'1 rotatesithe shaft 55 and the qmoistening {roller '58 carried thereoirare rotated, and the FF'QllQ1 :53 picks up Water from the pan 5? on its absorbent face and transfers a portion oi thesameto moistening roller 50 WlllClLlS in contact-with roller 53 andyrotatedthereby. -Ro'ller 'otl iin turn transfers some of the water 163115 1861 thereon to .moistening roller 4L9 with which it'isalso in contae-tand so causes the same to rotate as it rotates. Moisteningrolller is set in motion by theu'otationof the pinion 62 through the shaft 56 gttlld there-by &picks up a certain :amount of Water from the pan '58. The moistening rollers 49 and 54: they rotat coat the core member '87 with moisture on both isides ot the :same as passes between'them.

The gear 22 also has a cut out portion 96 which is suflicient to permit the cut out portion 9lto slide by as shaft 18 is always in rotation, and therefore gear 28 continues to rotate contin uously. The construction permits gear 22 and all of the parts connected therewith to come to a full stop during the rotation of gear 20 through the cut out portion 91 as it passes the cut out portion 96 of gear 22, and thereby the movement of the members 87 and 88 through the compression rollers 32 and 33 is stopped so that the tab completed and projecting from said compression rollers is cut by knife 39 which is operated by the eccentric 35, as it finishes up block 37 on each rotation of 35.

It is thus seen that the length around the gear 22 from one side of the out out 96 to the other side of the out out will determine the rotation of shaft 21 which in turn controls the rotation of shaft 24 and the two coinpression rollers 32 and 33 thereon. It is therefore necessary to only change this gear 22 toobtain a different length of tab to be out.

My machine and process are adapted to be used in the making of index tabs, hinged binders, or other articles of a similar nature common to the book binding art. Cloth, leather, paper or other suitable material may be used for the outside member 88, and any suitable material may be used for core member 87. I do not confine myself to the materials suggested or to the exact form of the machine shown or the process described, as I intend to cover the many variations in all of these which may be apparent to those well versed in the art.

Throughout the application the term tabhas been used, but the article made by this process and machine are merely strips which may be used as tags, tabsor for any suitable use for which folded index strip-material may be used. The gumming of the outside member may also be confined to the center portion so that the folded strip will be ungummed on the unstuck inside portion and the back or exterior portion when folded on the outside member may be lettered or printed in any desired manner, and the length of strip cut varied aocordingly.
